Target Lead. When engaging a moving target, the gunner must lead (aim infront of) the target to compensate for the movement. The amount of lead depends on thevelocity of the ammunition, target speed, and target angle, but he uses the standard leadto start the engagement. This only applies to the A3 when in degraded mode.(1) When using AP ammunition, the gunner uses a 5-mil lead from the center mass ofthe target. This rule is called the "gap lead." To apply gap lead, the gunner centers thetarget in the gap of the gun reticle. Figure 6-27 shows a BMP given a gap lead. The leadlines are shown as 2.5 mils long, except for the lead lines around the 1-mil circle, whichare 2 mils long.Figure 6-27. Gap lead applied to a moving BMP.6-30
